Oh hey I think I saw one of you guys in my cave.

BROTHER! IT'S BEEN TOO LONG!

In their lair I'd say the whole thing stinks. Outside of their lair I'd say they'd have disadvantage on sneak.

Ah yes, fair point. If the whole area reeks it makes senses. But most people would stay away from somewhere like that would be my thoughts. But adventurers aren't most people though, are they? Haha

Or since they are in the under dark, there are going to be many different kinds of smells. And I bet NONE are pleasant to smell. And lots of folks are not probably used to it, unless they live down there. And it's very rocky, cavernous. Full of all kinds of natural cover, plenty of opportunity to ambush. And the smell of them they may be used to, but it could also work as a "What is that awful fucking smell. John go check it out" John walks over to the smell and suddenly a few trog's come out and snatch John, beginning combat. And with the sounds of combat, surely it could bring more trogs. And they could swarm them. Or the idea of having the nearby area's of trog territory full of rotting remains and carcasses, along the walls. they could just lay in it and hide, awaiting any outsiders to come. And whilst busy, they could ambush there. Or hide in murky cesspools of gore and vicera. The scent of decay, rot and all of that is horrible. It's overpowering, especially the stench of feces and urine mixed in. And all of that is in a pretty closed in space/room. With no real naturally winds down there, the smell will not float away. Oh no, that will linger.. And the smell of it will cover any other smells, if you somehow smell how vile that is. It's easy to assume that most people will think "Oh great more decay and shit".

Granted Will just said the caves they dwell in have drafts, the draft is blowing in to the cave. That could also mean the scent of the hiding trogs could be masked with it. And before you could really smell it, due to the draft. They could be hiding nearby

You mean Trilobite?

Wait no I have one, if he had gotten here before me i would have had to say that troglo *bites*
